WebbThe histogram is a tool that represents the distribution of the intensities in an image. We used it in this exercise to define a threshold on the image, then segmenting the image into two classes. Furthermore, we can define several thresholds to obtain a segmentation with more than two classes, as for example in the image below.

In first step, the histogram is modified before segmentation. In fact, this step is considerably helpful in the segmentation of histogram and is effective in brightness preservation. Webb4 apr. 2009 · We use Wasserstein distance with exponent 1 to determine the dissimilarity between two histograms. The Wasserstein distance is a metric and is able to faithfully measure the distance between two histograms, compared to many pointwise distances. Moreover, it is insensitive to oscillations, and therefore our model is robust to noise. roth brothers jewelers

WebbFirst, the histogram is divided into several sub-histograms adaptively based on the heat conduction theory. By designing a metric called AHV, the background and non-background sub-histograms are distinguished, and then enhanced separately where more grayscales are allocated to non-background sub-histograms than background sub-histograms.

That’s most likely our fairly light text background but then the rest of it is kind of smeared out. An ideal segmentation histogram would be bimodal and fairly separated so that we could pick a number right in the middle.
